Description

Technical Field

[0001] The present invention relates to the technical field of intelligent cleaning equipment, and in particular to a swimming pool cleaning vehicle, in particular to a swimming pool cleaning vehicle with an internal driving device. Background Art

[0002] In the field of swimming pool cleaning, in recent years, swimming pool cleaning vehicles (also known as "pool cleaning locomotives", "underwater cleaning robots", "pool cleaning robots", etc.) as a professional swimming pool cleaning equipment have gradually been favored by users, and their importance has gradually become increasingly prominent. Especially in some private swimming pools, public swimming pools and other fields, this type of swimming pool cleaning vehicle can save labor costs and repeat daily cycle work. Therefore, it has gradually become the preferred robot locomotive for underwater cleaning of swimming pools.

[0003] However, the existing swimming pool cleaning vehicles are all in an underwater working environment. During the process of walking and climbing the wall, they are affected by the buoyancy of water and the impact of the water flow of the water spray during work, which leads to problems such as instability during the walking or climbing the wall process of the swimming pool cleaning vehicles.

[0004] Meanwhile, conventional pool cleaning vehicles generally require a separate motor to drive the roller brush to rotate in order to clean stubborn stains at the front or bottom. However, this structure is complex and increases the cost. In addition, the front motor is easily damaged during use, causing the machine to require repeated maintenance.

[0005] In a Chinese invention patent application, such as the publication number CN118704837A, the name “Swimming Pool Cleaning Robot”, and the publication date “September 27, 2024”, a structure of a swimming pool cleaning robot is disclosed; wherein the structure comprises: a main body

[11] , wheels, a roller brush, a motor

[19] , a motor

[19] gear, a first transmission gear

[172] , a second transmission gear

[173] and a roller brush gear

[174] , wherein the motor

[19] is arranged in the main body

[11] , the wheels, the roller brush, the first transmission gear

[172] , the second transmission gear

[173] and the roller brush gear

[174] are respectively rotatably arranged on the main body

[11] , and the motor

[19] gear, the first transmission gear

[172] , the second transmission gear

[173] and the roller brush gear

[174] are respectively rotatably arranged on the main body

[11] , and the motor

[19] gear, the first transmission gear

[172] , the second transmission gear

[173] and the roller brush gear

[0006]

[174] mesh with each other in sequence, the wheel is provided with an outer gear ring, the motor

[19] gear meshes with the outer gear ring, and the axis of the motor

[19] gear, the first transmission gear

[172] , the second transmission gear

[173] and the roller brush gear

[174] are all lower than the axis of the wheel in the vertical direction. Figure 2It can be clearly seen that the structure is mainly to drive the first gear, then the second gear, and then the roller brush gear through the motor gear. Although it can save gear motors, multiple gears overlap each other. When the gear box encounters sand and dust at the bottom of the pool, it is easy to make the gear box mesh loose, causing the gears to misalign and be easily damaged.

[0007] At the same time, the traditional underwater pool cleaning vehicle has running wheels or tracks arranged on both outer sides, which may easily cause the underwater robot to run aground or have difficulty in overcoming obstacles.

[0008] Therefore, how to make the underwater pool cleaning vehicle move more smoothly, easily overcome obstacles, and save manufacturing costs and processes is a technical problem that the industry urgently needs to solve. Summary of the invention

[0009] The present invention aims to overcome the deficiencies in the above-mentioned prior art and provide a swimming pool cleaning vehicle with an internal drive device, which is used to solve the problems of unstable walking, high cost, difficulty in overcoming obstacles, etc. of the existing swimming pool cleaning vehicles.

[0010] The technical solution adopted by the present invention is to provide a swimming pool cleaning vehicle with an internal driving device, which includes a swimming pool cleaning vehicle body, a filtering device is arranged inside the swimming pool cleaning vehicle body, a water inlet connected to the filtering device is arranged at the bottom of the swimming pool cleaning vehicle body, and a water outlet is arranged on the side or / and the top of the swimming pool cleaning vehicle body.

[0011] During the cleaning process, the sewage in the swimming pool is sucked in from the water inlet at the bottom. When it flows through the filter device, the filter device can absorb or collect the dirt in the sewage. The filtered water flows out from the outlet, thereby achieving the cleaning of the swimming pool or the ordinary pool.

[0012] A roller brush is arranged at the front end of the main body in the direction of travel, and the roller brush brings water and garbage into the water inlet arranged at the bottom of the main body during cleaning.

[0013] When a swimming pool or ordinary water pool is not used for a period of time, cotton-like dirt tends to accumulate at the bottom of the swimming pool or ordinary water pool; some mud and dust also tend to accumulate, so adding a roller brush to scrape and collect the dirt at the bottom makes the cleaning effect better.

[0014] Both sides of the body are provided with running wheels, which provide the walking power of the swimming pool cleaning vehicle. Under normal working conditions, the running wheels are arranged on the two sides of the body, and each side is provided with a front running wheel and a rear running wheel.

[0015] The walking wheels include a front wheel and a rear wheel. A driving motor is arranged inside the swimming pool cleaning vehicle body. The motor output shaft of the driving motor is interconnected with the rear wheel and provides power to the rear wheel. Alternatively, the motor output shaft of the driving motor is interconnected with at least one conversion component, and the conversion component is connected to the rear wheel and provides power to the rear wheel.

[0016] The conversion component is at least one conversion gear.

[0017] The rear wheel drives the front wheel and the roller brush to rotate simultaneously and in the same direction through a first transmission component, and the first transmission component is an annular belt structure.

[0018] Through one motor, four traveling wheels and roller brushes are driven to rotate simultaneously and in the same direction, which has a simple structure and reduces manufacturing costs and labor costs; the simultaneous rotation of the four traveling wheels also makes the walking process more stable.

[0019] Furthermore, the front wheel includes a front wheel axle fixed to the body, and a front wheel hub arranged at the end of the front wheel axle, and a first rotating shaft gear is arranged on the end of the front wheel axle or on the inner side of the front wheel hub; the first rotating shaft gear is arranged around the front wheel axle at the center of the circle of the front wheel hub.

[0020] The rear wheel includes a rear wheel axle fixed to the body, and a rear wheel hub arranged at the end of the rear wheel axle, and a second rotating shaft gear is arranged on the end of the rear wheel axle or on the inner side of the rear wheel hub; similarly, the second rotating shaft gear is arranged around the rear wheel axle at the center of the circle of the rear wheel hub.

[0021] A driving gear is arranged on the output shaft of the motor, and the driving gear is meshed with the second rotating shaft gear and drives the second rotating shaft gear to rotate, and the second rotating shaft gear drives the first rotating shaft gear to rotate through the first transmission assembly.

[0022] Furthermore, the first transmission component is a transmission crawler, the outer circumference of the transmission crawler is provided with a first transmission tooth, and the inner circumference of the transmission crawler is provided with a second transmission tooth;

[0023] The second transmission gear is respectively meshed with the first rotating shaft gear and the second rotating shaft gear, thereby driving the front wheel and the rear wheel to rotate simultaneously.

[0024] Furthermore, a roller brush gear is provided at the side end of the roller brush, the roller brush gear is fixed to one of the ends of the roller brush, and the roller brush is rotatably arranged at the front lower position of the body, and when the roller brush gear rotates, it can drive the roller brush to rotate together.

[0025] Furthermore, the first transmission tooth meshes with the roller brush gear, that is, when the transmission track moves, the first transmission tooth arranged on the outer periphery of the track meshes with the roller brush gear, which can drive the roller brush gear to rotate, thereby driving the roller brush to rotate.

[0026] Alternatively, a first gear ring is provided on the front wheel hub, and the roller brush gear is meshed with the first gear ring.

[0027] Through the above arrangement, the roller brush gear can be driven by the hub of the traveling wheel or by the first transmission tooth of the transmission assembly, which can achieve the purpose of the present invention in which a single motor can drive the traveling wheel, transmission belt and roller brush.

[0028] Furthermore, the first transmission assembly is arranged on one side of the swimming pool cleaning vehicle body in the traveling direction, and drives the front wheel, rear wheel and roller brush on the side to rotate simultaneously and in the same direction.

[0029] Furthermore, it also includes a second transmission assembly, which is arranged on the other side of the walking direction of the swimming pool cleaning vehicle body and drives the front wheel and the rear wheel on the other side to rotate simultaneously and in the same direction.

[0030] Furthermore, a tensioning wheel is disposed below the first transmission assembly and / or the second transmission assembly, and the tensioning wheel is fixed to the body and is used to adjust the tension of the first transmission assembly and / or the second transmission assembly.

[0031] Preferably, two tensioning wheels are arranged on each side, with a first tensioning wheel arranged at the front and a second tensioning wheel arranged at the rear. The first tensioning wheel and the second tensioning wheel are kept consistent in horizontal directions so that they are arranged on the same horizontal line.

[0032] Furthermore, a bottom plane of the first transmission assembly and / or the second transmission assembly is lower than a bottom plane of the swimming pool cleaning vehicle body.

[0033] That is, the first transmission assembly and / or the second transmission assembly are lower than the bottom of the pool cleaning vehicle, so that when encountering an obstacle, the first transmission assembly and / or the second transmission assembly can directly drive over it without getting stuck at the bottom.

[0034] Furthermore, the first transmission assembly and / or the second transmission assembly are arranged inside the two sides of the swimming pool cleaning vehicle body under the orthographic projection, and the running wheels are arranged outside the swimming pool cleaning vehicle body.

[0035] In this way, the driving structure of the swimming pool cleaning vehicle includes not only the walking power of the walking wheels, but also the power of the first transmission assembly and / or the second transmission assembly, so that the swimming pool cleaning vehicle is more stable when climbing a wall and has better effects in climbing slopes and overcoming obstacles.

DETAILED DESCRIPTION

[0053] The drawings of the present invention are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0054] Example 1

[0055] like Figure 1-10 As shown, the present embodiment provides a swimming pool cleaning vehicle with an internal driving device, which includes a swimming pool cleaning vehicle body. A filtering device (not shown in the figure) is arranged inside the swimming pool cleaning vehicle body. In the present embodiment, the filtering device is specifically a filtering basket with filter holes arranged on the wall. A water inlet connected to the filtering device is arranged at the bottom of the swimming pool cleaning vehicle body 1, and a water outlet 2 is arranged on the side or / and the top of the swimming pool cleaning vehicle body 1.

[0056] During the cleaning process, the sewage in the swimming pool is sucked in from the water inlet at the bottom, and when it flows through the filter basket of the filter device, the filter device can absorb or collect the dirt in the sewage, and the filtered water flows out from the water outlet 2, thereby achieving the cleaning of the swimming pool or the ordinary pool. After the cleaning is completed, it is only necessary to pour out the garbage or dirt in the filter device and clean it.

[0057] A roller brush 4 is provided at the front end of the main body 1 in the direction of travel, and the roller brush 4 brings water and garbage into the water inlet provided at the bottom of the main body 1 during cleaning.

[0058] When a swimming pool or ordinary pool is not used for a period of time, cotton wool-like dirt is easily accumulated at the bottom of the swimming pool or ordinary pool; some mud and dust are also easily accumulated, so the roller brush 4 is added to scrape and collect the dirt at the bottom, so that the cleaning effect is better.

[0059] The two sides of the body 1 are provided with running wheels 3, and the running wheels 3 provide the running power of the swimming pool cleaning vehicle. Under normal working conditions, the running wheels 3 are arranged on the two sides of the body 1, and each side is provided with one front wheel and one rear wheel, for a total of four running wheels 3. Fig.10 The structure diagram of the traveling wheel 3 is shown in FIG. 2 for reference.

[0060] Figure 2 In, yes Figure 1 A three-dimensional diagram from another angle. Figure 3 is Figure 2 On the basis of the above, a schematic diagram showing the transmission structure in the rear wheel of the running wheel 3 is shown. The running wheel 3 includes a front wheel and a rear wheel. A driving motor (not shown in the figure) is arranged inside the swimming pool cleaning vehicle body 1. The motor output shaft of the driving motor is connected to one of the rear wheels and provides power to the rear wheel. The two rear wheels can also be driven at the same time (only the rear wheel axle can be driven, which is not shown in the structural picture). The rear wheel drives the front wheel and the roller brush 4 to rotate simultaneously and in the same direction through the first transmission component 11. The first transmission component 11 is an annular belt structure.

[0061] In this embodiment, one motor is used to drive four traveling wheels 3 and roller brushes 4 to rotate simultaneously and in the same direction, which has a simple structure and reduces manufacturing and labor costs. The simultaneous rotation of the four traveling wheels 3 also makes the walking process more stable.

[0062] In one embodiment, the front wheel includes a front wheel axle fixed to the body 1, and front wheel hubs arranged at the ends of both sides of the front wheel axle, and a first rotating shaft gear 13 is arranged on the end of the front wheel axle or on the inner side of the front wheel hub; the first rotating shaft gear 13 is arranged around the front wheel axle at the center of the circle of the front wheel hub.

[0063] In this embodiment, the front wheel hub refers to the entire circular component whose inner profile of the running wheel 3 supports the tire (or wheel surface) and whose center is mounted on the shaft. In this embodiment, it can be made of metal or rubber or other materials. It is also called a wheel rim, a wheel, a tire bell, etc. There are many types of wheel hubs according to different diameters, widths, molding methods, and materials. They are all known public technologies and will not be described in detail in this embodiment.

[0064] The rear wheel includes a rear wheel shaft fixed to the body 1, and a rear wheel hub disposed at the end of the rear wheel shaft, and a second shaft gear 14 is disposed at the end of the rear wheel shaft or on the inner side of the rear wheel hub; similarly, the second shaft gear 14 is disposed around the rear wheel shaft at the center of the circle of the rear wheel hub. Similarly, the rear wheel hub has the same structure and material as the front wheel hub.

[0065] The motor output shaft is provided with a driving gear 7 , which meshes with the second rotating shaft gear 14 and drives the second rotating shaft gear 14 to rotate. The second rotating shaft gear 14 drives the first rotating shaft gear 13 to rotate through the first transmission assembly 11 .

[0066] In one embodiment, the first transmission component 11 is a transmission crawler, the outer circumference of the transmission crawler is provided with first transmission teeth 15, and the inner circumference of the transmission crawler is provided with second transmission teeth 16;

[0067] The second transmission gear 16 is meshed with the first shaft gear 13 and the second shaft gear 14 respectively, thereby driving the front wheel and the rear wheel to rotate simultaneously.

[0068] In one embodiment, a roller brush gear 5 is provided at the side end of the roller brush 4, the roller brush gear 5 is fixed to one of the ends of the roller brush 4, and the roller brush 4 is rotatably arranged at the front lower position of the main body 1, and when the roller brush gear 5 rotates, it can drive the roller brush 4 to rotate together.

[0069] like Figure 7 , Figure 8 , Fig. 9 As shown, in one embodiment, a first gear ring 17 is provided on the front wheel hub, and the roller brush gear 5 is meshed with the gear ring.

[0070] In this embodiment, the first gear ring 17 is arranged on the inner side of the outer circumference of the front hub, that is, close to the inside of the body 1.

[0071] like Figure 4 , Figure 5 , Figure 7 , Fig. 9As shown, in a specific implementation, a driving gear 7 is provided on the motor output shaft, and the driving gear 7 is meshed with the second rotating shaft gear 14 and drives the second rotating shaft gear 14 to rotate. The second rotating shaft gear 14 drives the first rotating shaft gear 13 to rotate through the first transmission assembly 11. During the rotation of the first rotating shaft gear 13, the first gear ring 17 also rotates, and then the roller brush gear 5 meshed with the first gear ring 17 is also driven to rotate by the first gear ring 17, thereby achieving the purpose of driving the walking wheel 3 and the roller brush 4 to rotate at the same time by one motor.

[0072] In one embodiment, the first transmission assembly 11 is disposed on one side of the swimming pool cleaning vehicle body 1 in the direction of travel, and drives the front wheel, rear wheel and roller brush 4 on the side to rotate simultaneously and in the same direction.

[0073] like Figure 4 , Figure 5 As shown, in one embodiment, a second transmission assembly 12 is further included. The second transmission assembly 12 is arranged on the other side of the walking direction of the swimming pool cleaning vehicle body 1, and simultaneously drives the front wheel and the rear wheel on the other side to rotate simultaneously and in the same direction.

[0074] The transmission assembly (in this embodiment, the transmission crawler) can be provided with only one, or two can be provided on both the left and right sides. In this embodiment, transmission assemblies (i.e., the first transmission assembly 11 and the second transmission assembly 12) are provided on both sides, so that the swimming pool cleaning vehicle is more stable and does not deviate during the driving process. If only one side is provided, and the other side is loose and free, the wheels on the other side can swing freely during the walking process, which is easy to cause direction deviation, etc.

[0075] like Figure 4 , Figure 5 As shown, when the first transmission assembly 11 and the second transmission assembly 12 are changed based on the present embodiment, there is no necessary position designation. When the left side of the swimming pool cleaning vehicle in the forward direction is defined as the first transmission assembly 11, the right side of the swimming pool cleaning vehicle in the forward direction is defined as the second transmission assembly 12; when the right side of the swimming pool cleaning vehicle in the forward direction is defined as the first transmission assembly 11, the left side of the swimming pool cleaning vehicle in the forward direction is defined as the second transmission assembly 12. The transmission structure, effect, etc. are all consistent, and are also supported and protected by the present invention.

[0076] In one embodiment, a tensioning wheel 6 is further provided below the first transmission assembly 11 and / or the second transmission assembly 12 , and the tensioning wheel 6 is fixed on the main body 1 and is used to adjust the tension of the first transmission assembly 11 and / or the second transmission assembly 12 .

[0077] The function of the tensioning wheel 6 is to adjust the tightness of the transmission crawler belt with the tensioning wheel 6 after the transmission crawler belt is installed.

[0078] Preferably, two tensioning wheels 6 are arranged on each side, with a first tensioning wheel 6 arranged at the front and a second tensioning wheel 6 arranged at the rear. The first tensioning wheel 6 and the second tensioning wheel 6 are kept consistent in horizontal directions so that they are arranged on the same horizontal line.

[0079] In one embodiment, the bottom plane of the first transmission assembly 11 and / or the second transmission assembly 12 is lower than the bottom plane of the pool cleaning vehicle body 1 .

[0080] That is, the first transmission assembly 11 and / or the second transmission assembly 12 are lower than the bottom of the pool cleaning vehicle, so when encountering an obstacle, the first transmission assembly 11 and / or the second transmission assembly 12 can directly drive over it without getting stuck at the bottom.

[0081] In one embodiment, the first transmission assembly 11 and / or the second transmission assembly 12 are arranged inside both sides of the swimming pool cleaning vehicle body 1 under orthographic projection, and the walking wheels 3 are arranged outside the swimming pool cleaning vehicle body 1.

[0082] In this way, the driving structure of the swimming pool cleaning vehicle includes not only the walking power of the walking wheels 3, but also the power of the first transmission assembly 11 and / or the second transmission assembly 12, so that the swimming pool cleaning vehicle is more stable when climbing a wall, and has better effects in climbing slopes and overcoming obstacles.

[0083] Example 2

[0084] like Figure 3 As shown, this embodiment provides a swimming pool cleaning vehicle with an internal drive device, wherein the first transmission assembly 11 is a transmission crawler, the outer circumference of the transmission crawler is provided with a first transmission tooth 15, and the inner circumference of the transmission crawler is provided with a second transmission tooth 16 ( Figure 7 As a schematic diagram of this embodiment, the positional relationship between the first transmission tooth 15 and the second transmission tooth 16 can be seen.

[0085] exist Figure 3 It can also be clearly seen that the roller brush gear 5 and the first transmission assembly 11 are in contact with each other, so that the roller brush gear 5 and the first transmission teeth 15 arranged on the outer circumference of the first transmission assembly 11 are meshed with each other. That is, when the transmission track is moving, the first transmission teeth 15 arranged on the outer circumference of the track are meshed with the roller brush gear 5, and the roller brush gear 5 can be driven to rotate by the first transmission teeth 15, thereby driving the rotation of the roller brush 4. Other structures are consistent with the first embodiment and have the same technical effects as the first embodiment, and are not described one by one here.

[0086] Example 3

[0087] In this embodiment, the first transmission component 11 and / or the second transmission component 12 is a metal chain structure (not shown in the figure), which can also achieve the purpose of the present invention. Other structures are consistent with those of Example 1 and have the same technical effects as those of Example 1, and will not be described one by one here.

[0088] Example 4

[0089] like Figure 6 , Figure 7 As shown, in this embodiment, the walking wheel 3 includes a front wheel and a rear wheel, and a drive motor is arranged inside the swimming pool cleaning vehicle body 1. The motor output shaft of the drive motor is interconnected with at least one conversion component, and the conversion component is connected to the rear wheel and provides power for the rear wheel.

[0090] In this embodiment, the conversion component is specifically a conversion gear 19, which is connected to the drive gear 7 at the end of the motor output shaft and the second shaft gear 14 ( Figure 6 , Figure 7 As a schematic diagram of this embodiment, the meshing connection relationship between the driving gear 7 and the second shaft gear 14 can be clearly seen).

[0091] In this embodiment, the number of conversion gears 19 is specifically one, and multiple gears can also achieve engagement and conversion, but the more gears there are, the more complicated the structure is, so one conversion gear 19 is the best and simplest.

[0092] Alternatively, the conversion gear 19 is simultaneously connected to the driving gear 7 at the end of the motor output shaft and the second gear ring 18 provided on the rear wheel hub.

[0093] In this embodiment, the second gear ring 18 is arranged on the inner side of the outer circumference of the front hub, that is, close to the inside of the body 1.

[0094] During operation, after the motor is driven, the driving gear 7 at the end of the motor output shaft rotates, thereby driving the conversion gear 19 to rotate, and the conversion gear 19 then drives the second gear ring 18 to rotate. The second gear ring 18 is the outer periphery of the rear wheel hub, thereby driving the rear wheel hub to rotate at the same time.

[0095] The other structures are consistent with those of the first embodiment and have the same technical effects as those of the first embodiment, and will not be described in detail here.

[0096] The swimming pool cleaning vehicle with an internal drive device provided in this embodiment has the following main advantages:

[0097] 1. The roller brush does not require a separate motor drive, saving materials, manufacturing costs and processes;

[0098] 2. Through the ingenious connection of the transmission component with the travel wheel and the roller brush, one motor can drive the transmission component, travel wheel, roller brush and other multiple combinations to rotate simultaneously and in the same direction. The structure is simple and the walking process is more stable.

[0099] 3. The first transmission assembly and / or the second transmission assembly are arranged inside the two sides of the swimming pool cleaning vehicle body and are lower than the bottom of the swimming pool cleaning vehicle, so that the swimming pool cleaning vehicle is more stable when climbing a wall and has better effects in climbing a slope and overcoming obstacles.

[0100] 4. The transmission track can be provided with transmission teeth on both sides to drive the rotation of the roller brush, and the rotation of the roller brush can also be driven by providing a gear ring on the walking wheel. The structure is simple, and the implementation method is diversified and humanized.
